This chapter contains a general description of EPS 3501 XL.
General description
EPS 3501 XL is a high quality, high precision power supply for electrophoresis
applications that require advanced programming and high voltage.
EPS 3501 XL is primarily designed for techniques using programming in several phases
and/or voltage gradients:
• 2-D (Two dimensional) electrophoresis using Multiphor II Electrophoresis System
• IEF (Isoelectric focusing) using Immobiline™ or carrier ampholytes such as
CleanGel™ and ExcelGel™
• Flatbed SDS-PAGE (Polyacrylamide Gel Electrophoresis) or flatbed native PAGE
EPS 3501 XL is also suitable for:
•DNA sequencing
• Agarose electrophoresis
•Electroblotting
• DNA pulsed field electrophoresis
Nine programs each with up to nine phases can be saved. Limiting values for voltage,
current and power as well as voltage gradients can be programmed for precise control
of the electrophoresis. The EPS 3501 XL automatically switches over the controlling
parameter according to programmed limits and gradients and conductivity variations
in the system.
Two electrophoresis units can be connected to EPS 3501 XL and run with the same
programmed method at one time.

Key Label Description
set enter Press set enter to enter a value or choice, confirm this if
valid, and move programming to the next field. Valid
values are voltage 35–3 500 V, current 1–400 mA, power
1–200 W, time 0:01–500 h, volthours 1–500 000 Vh,
milliampere-hours 1–25 000 mAh.
In the RUN mode, pressing set enter shows the
programmed parameters for the actual run. In addition,
set enter allows you to make changes in the program
during a run after first pressing pause continue.
After a run, when in END mode, pressing set enter puts
the instrument into SET, its programming mode.
-Press to change the parameter, value or other
choice in the field which is blinking. Numerical values are
changed in an accelerating manner when a key is held
down. Clicking a key changes the value in preset
increments. Parameters or units (e.g. Vh) and choices (e.g.
Yes/No) are changed with one key push. The keys can also
be used to switch between time and volthours in RUN,
PAUSE and END. The values scroll i.e. they automatically
change from maximum to minimum value or vice versa.
run Press run to start the run and put the program into RUN
mode. The current values for voltage, current and power
are shown on the display. The elapsed time, volthours or
milliamperehours are also displayed. Switch between
these last three parameters with
pause
continue
Press pause continue to put the instrument in PAUSE
mode and switch off the voltage. The display shows the
status of the run at the time the key was pressed. pause
continue only operates in RUN mode. Time, integrated
voltage and integrated current are retained.
In the PAUSE MODE mode, set enter can be used to make
changes in the program. Return to RUN mode by pressing
pause continue or by pressing run.
STOP Press STOP to stop the run and put the instrument in END
mode. The voltage is switched off and the end parameters
are displayed. Switch between time, integrated voltage
and integrated current by pressing . A run cannot be
continued after pressing STOP. Press run to run the same
method again or press set enter to choose another
program, program a new method or make changes in an
existing method.

power cord must always be easy to disconnect.
WARNING
Hazardous biological agents during run. When using hazardous
biological agents, flush the entire system tubing with bacteriostatic
solution followed by a neutral buffer and finally distilled water, before
service and maintenance.
WARNING
Avoid spilling liquids on the body of the instrument. If large volumes of
liquid have penetrated the casing of the instrument and come into
contact with the electrical components, immediately switch off the
instrument and contact an authorized service technician.

Power failure
The result of a power failure depends on which unit that is affected.
2.4 Built-in safety features
The power supply has the following built-in safety functions:

position. If required, disconnect the mains power cord. The run is
interrupted immediately.
Power failure to... will result in...
EPS 3501 XL The run is interrupted immediately, in an undefined state
Function Description
Functional earth
leakage
Should the power supply be connected to an electrophoresis
unit that has a leakage path to earth, the EPS 3501 XL will
detect this fault and turn off the high voltage.
Start current check The power supply checks that the resistance is not higher
than a specified limit at a low safety voltage (<40V). If this
resistance is too high, the high voltage is turned off.
Too high resistance can be caused by for example:
- an electrophoresis unit incorrectly connected
- use of buffer with exremely low conductivity
This function can be disabled to perform certain applications,
see Electrophoresis Power Supply EPS 3501 XL User Manual.
